STAND-FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 540,823, dated June 11,1895.

Application filed November 14, 1894. Serial No. 528.761- (NO model.)

To all whom it may concern,.-

Be it known that we, ALLEN S. VVASS, residing at Bloomfield, and STEPHENA. DAVIS, re-

siding at Newark, in the county of Essex and Y State of New Jersey,citizens of the Unitedv States, have invented certain new and usefulImprovements in Stands or Supporting-` Frames for Sewing-Machines; andwe do hereby declare the following to be a full, clear, and exactdescription lof the invention, lsuch as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters and numerals ofreference marked thereon, which form a part of this specification.

The objects of this invention are to reduce the cost of construction, toprovide a more simple device, and one which will secure an easiermovement of parts; to prevent injury to the hands when lowering themachine head into the case, and to secure other advantages and resultssome of which will be referred to hereinafter in connection with thedescription of the working parts. Y

The invention consists in the improved stand orfsupporting frameforsewing maf chines and in the arrangements and combinations of parts,Substantially as will be hereinafter described and finally embraced inthe clauses of the claim.

Referring to the accompanying drawings, in which like letters andnumerals of reference indicate .corresponding parts in each of theseveral views, Figure l is a front elevation of the improved stand orsupporting-frame, showing the sewing-head of the machine in outline.Fig. 2 is a sectional view showing the cover open and thesewing-head-supporting device at its elevated position. Fig. 3 is asimilar sectional view showing saidcover closed and the head- Supportlowered. Fig. 4 is a section taken at line x, showing the means employedfor raising a certain front panel; and Fig. 5 is a detail showing insection at line y the ways or tracks and the lower part of thevertically-movable sewing-head support.

In said drawings, a, indicates the stand or frame, which consists of alow metal-frame having side Standards` a', which pro vide bearings forthe fly wheel, a, its covering frame, of", and the treadle shaft, am',in any suitable and usual manner.

The side standards extend about half way up the stand and are connectedat the rear by a curved brace, am, which is centrally attached to therear board of the upper wood work.

The upper part of the stand, et, is of wood work, and fo'r convenienceof description, we may term it the case, b. This consists of paneledplates, b', b, b", b,'which are united together at their edges in anysuitable manner to form a protecting inclosure, and are, together,secured` to and are adapted to be removed from the'top of the metalframe without dismembering or dissociating the parts of said metalframe, or changing the relation of the side drawers to the case. Byarranging 'the case on the top of the iron frame, the side plates, b,resting on the standards, a', a', and

the rear plate resting on the arched top of the brace, we are enabled toattach the iron brackets or supporting plates, c, c, which carry theside drawers, c', directly upon the wooden sides of the case, thedrawers engaging said side plates, b, or pieces applied thereto, thusproducing a more compact appearance to the wood work and reducing thecost of labor, zc., involved when the said brackets have been attachedto thev metal frame, which, in that 'hinged at its upper edge, asv shownin Fig. 4,

and is so coupled to the vertically movable sewing-head support, d, asto turn on its hinges as the lid, 0, is raised and the support movesvertically, or approximately vertically, within the case, as will beunderstood upon reference to said Fig. 4, where said support is shown tobe provided with a screw eye, e, and link,f, and the back of the panel,5, with a vertical rod g, bent at its opposite ends and thereat providedwith perforated feet by which said rod is secured to the panel and heldaway therefrom so that the link may slide on said rod.

As the support, d, rises 'to its elevated position, shown in Figs. 2 and4, and draws on the link, the latter slides on the rod and the ICOboard, j, underlying the inner ends of said transverse pieces; ironbrackets, 7c, bracing said parts i and j, and holding the same at rightangles; cleats or stays, l, at the rear ot` said vertical plate whichengage the sides of guide ways or tracks, m; rollers, m', fastened 011the lower end of the said vertical board at the front, as shown in Figs.2 and 3, and bearing on the outer face of said ways or tracks, m, androllers, m, bearing on the rear or back of said tracks and stationed onthe cleats or stays, Z, the said rollers, m', m, serving to prevent thevertically movable support from binding on its ways.

The means for moving the support are in connection or train with thehinged lid, o, which not only serves to close the opening in the topplate, b", when the sewing head is in the case, but as a hand lever bywhich the operator sets the mechanism for lowering or raising thesupport, d, in motion. Said lid, o, is hinged at p, to the top plate andat its rear edge, at q, receives a connecting rod, o", by which it isjoined to a sectional lever arm, s. Said arm s, in turn is arranged atthe back of the rear plate, b", on a bolt or shaft, t, having pivotaland angular bearings, the pivotal bearings lying in the said rear plate,11', a suitable journal box being provided for the same. On the innerend of the shaft or bolt, within the case, is another arm, u, workingwilli the bolt, t, and arm, s, the three said parts being essentially abell crank. The free end of the arm, u, is coupled to the verticalsupporting plate or board, j, by a connecting rod, u, said board beingblocked out at the rear to bring the parts into or close to a commonplane of action, as will be understood.

The arm,s, is sectional, as above described, and as shown in outline inFig. 3,so as to prevent the lid weighted by the sewing head, frompressing the fingers against the top plate, b.

The lever-arm section, s', in immediate connection with the lid, 0, ispivoted at 3, upon the section, s, and engages a pin, 4, of the lattersaid section, so that the weight of the descending sewing head holds thetwo sections rigid and inline, but when the said head has nearly arrivedat the lower limit of its movement and the lid, o, is about to engagethe top plate, a spring 5, takes the major part of the weight, and thearm, u, next impinges upon a bearing or fixture, u', and is thus broughtto a stop. A continued movement ot' the lid is allowed, however, by thejointed arm so that thelid finally rests fully upon the top plate. Thelast inch or two of its movement at its end away from the hinges beingdue to the joint in the arm,s, and being without the pressure of thesewing head, the said lid will not injure the fingers caught thereunder,as will be evident. The spring, 5, is in linked sections, as shown inFig. 2, so that, when not under tension, the sections may fold and thusnot interfere with a full movement of the-arm.

To enable the descending support to clear the driving wheel in itsdownward movement and thus allowa greater movement ofthe support withoutinterference and a higher disposition of the said driving wheel in theframe, we have' made the ways, m, m, on which the head support slides,inclined, as shown in Figs. 2 and 3, and the said support is therebyguided away from the said driving wheel.

In operating the device, on raising the lid, o, the connecting rod isdrawn upon so that its sections are first brought into rigid relation,and then the arm as a whole is turned with the bolt, t, and outer arm,u. This latter arm and its connecting rod, throw the support to itsupper position on the waysmz, and the top plate, d', is brought Iiushwith the frame top plate, b. At the same time, the hinged front panel israised as already described. A reversal of the parts lowers the headinto the case, where it is protected.

I-Iavin g thus described the invention, what we claim as new is l. In asewing machine stand, the combination with case having the open topplate l1', and the hinged lid, a sewinghead support arranged in saidcase, connections of said lid and sewing head support whereby when saidlid is open the said support. is raised'to bring the sewing head abovethe top plate, a loose joint being provided in said connections to avoida direct pressure of the sewing head and attachments upon the lid nearthe limit of its closing movement, substantially as set forth. 2. Theimproved sewing machine stand or supporting frame herein described, inwhich is combined with the iron frame and case having a hinged frontpanel, hm", a vertically movable sewing head support connecting with thelever-like lid, said lid and connections, a link and eye, f, c, securedto the said vertically movable support and a rod, g, bent at oppositeends and thereat engaging the back of said panel, said link sliding onsaid rod, substantially as set forth.

3. In a stand for sewing machines, the oombination with ways, m, m, of avertically movable sewing head support, and a train of levers foroperating the saine, said train including therein a sectional arr'n oneSection of which is free to work on the other at the limit of movement,so that the hand lever of the train-will not press the hand between itand adjacent parts, substantially as set forth.

4. In a sewing machine stand, the combinaxoo IIO

tion With the case having the open top plate, I

, b', and hinged lid to close the opening therein, a sewing head supportmovable within said case, a train of connections of said lid with saidsewing head support, one of the arms or sections of said train beinglimited in its movement to prevent a continued descent of the supportand another arm or section of said train being jointed to admit acontinued movement of the lid devoid of the Weight of the sewing headand attachment, and means for limiting the descent of the support,substantially as set forth.

5. The combination, in a sewing machine stand, of a vertically movablesewing head support, a lid, a bell crank and connections of said crankwith the lid and support, one of the arms of said crank being in pivotalsections one of which is provided with a bearing projection, 4,substantially as set forth.

6. In a sewing machine stand or supporting frame, the combination Withthe sewing head support, having rollers, a `lever-like lid -and hingedfront panel, of a bell crank, andconnections in train with said lid andsupport and links connecting said front panel and support, whereby, whenthe lid is raised and the bell crank turned on its pivot or fulcrum, thesupport will be raised and the panel turned in- Ward simultaneously,substantially as set forth.

In testimony that we claim the foregoing We have hereunto set our handsthis 18th day of October, 1894.
